Inventor: FIRMIN ROBERT L
IPC: G01B11/00
Filed: 2019-01-06
Abstract: A digital-optical tracking device and methods for tracking and timing swimmers are disclosed. The digital-optical tracking device is waterproof and submersible, and includes a stereo optical system that takes digital stereo images of an underwater region. The stereo optical system includes at least two optical elements, each of which forms an image in the stereo image. The tracking methods involve repeatedly determining distances to swimmers by measuring distances between stereo copies of the swimmers in successive, time-stamped stereo images. The methods may use predictive algorithms to determine regions of interest within the stereo images in which the swimmers are likely to be found. Once tracking data is established, it is displayed to the swimmers during their workouts and may be shared among multiple trackers in a peer-to-peer configuration, saved for later reference, and sent to a coach station or stations for real-time analysis.

Title: Substrate treatments
Inventor: RAHMATHULLAH AFLAL
IPC: B01D39/20
Filed: 2019-02-14
Abstract: The current technology relates to substrate treatments, treated substrates, and filters. Treated substrates can have a treated surface that defines a pattern and/or gradient among untreated surface areas. A treated surface area can have a higher roll off angle for a 50 µL water droplet when the surface is immersed in toluene that the untreated surface areas. Substrates can be treated by, for example, exposing a substrate surface and/or fibers to ultraviolet (UV) radiation. UV radiation can be applied to surfaces via a mask, lens, waveguide, reflector, as examples. UV radiation can be applied to surfaces at varying intensities, which can create a treatment gradient.

Abstract: The invention relates to methods of extraction of metal compounds, specifically - to tools for uranium hexafluoride (UF6) conversion into uranium dioxide (UO2) ceramic powder (up to 5% enrichment of U235) by applying method of reductive pyrohydrolysis. Summary of the invention: The reaction chamber is a shell with upper and lower heads, comprising upper filtration area, equipped with metalceramic filters, regenerating nitrogen, the first reaction zone for conversion of uranium hexafluoride into uranyl fluoride, the second reaction zone with gas-distribution grid for building up fluidization layer for reduction of uranyl fluoride to uranium dioxide with a nozzle of steam, hydrogen and nitrogen supply On the side walls of the first reaction zone of the reaction chamber shell there are two nozzles located symmetrically for uranium hexafluoride, hydrogen and water steam supply. The chamber is equipped with a device for discharge of powder. Nozzles for uranium, hydrogen and water steam supply may be made movable vertically. Also, nozzle may perform separately as an inlet for supply of uranium hexafluoride, and the other as an inlet for supply of hydrogen and water steam. The proposed design of the reaction chamber allows solving the task of increasing time between overhauls of the reaction chamber, operating life of filtration components and increasing of its performance at cost of exclusion of semi-product accumulation.
